“[In Spem in alium] Parrott's sure touch tells in the form: the first entry is clear and confident...the first Mexican wave spreads inexorably, the arrival on the second tutti rings out like a clarion-call, the antiphonal section doesn't flag, the initial 'Respice' is solemn and arresting, and the final tutti gloriously full-bodied.” Gramophone Magazine, February 2010
